tweak is the right word....tweaker might do the mod.

Dont do it. First of all you will be messing with the ECU's capability of controlling air fuel ratios. Second, your O2 sensor will have the last say in the ECU correcting for the adjustment. AFM is a very serious and touchy component. I thought I could do the mod with my upgrades and modifications after 2 years of telling people not to mess with it. 3 weeks later my #4 cylinder spit its rings out. Piston looked like it had been hit with a blowtorch...not just #4 but all of them.

Do yourself a favor and leave the EFI sensors set where they are.

Just my $.02 after trying it and spending alot more of fixing things.

Call LCE and talk with their techs about it. Even they will tell you not to mess with it unless the engine is so heavily modified that it wont start with stock settings.
